3 Claims.

The present invention relates to closures for tooth paste tubes and thelike and has for its primary object to providean upstanding dischargeneck for the tube having a discharge opening therein and provided with aclosure'slidably mounted over the neckfor controlling passage throughthe discharge opening and providing Operating means for said closure inthe form of a ring operable b-y a rotary movementto actuate the slidingclosure.

A further object is toy provide a device of `this Character of simpleand practical construction, Whichis neat and attractive in appearance,relatively inexpensive to manufacture and otherwise i Well adapted forthe purposes for which the same is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the aocompanying drawing forming part hereof, wherein likenumerals refer to like parts throughout, and in which- Figure 1 is afragmentary side elevational View of a paste tube showing the closuremounted in position on lthe neck of the tube. i

Figure 2 is a similar View taken substantially at `fight angles; fromFigure 1.

Figure 3 is a top plan View.

Figura 4 is a Vertical secticnal view.

Figure 5 is a transverse sectional view taken substantially on a line5-5 of Figure 1, and

Figure 6 is av detail showing the pin and slot connection between thesliding closure and the rotary Operating ring.

Referring now to the drawing in detail, wherein for the purpose ofillustration I have disclosed a pr-eferred embodiment of the invention,the numeral 5 designates a conventional type of paste tube having adischarge neck 6 rising therefrom, the neck embodying two flat parallelside walls 1 and a rounded top 8 merging with the remaining side walls9. The top of the rounded portion of the neck is formed with adischargeopening lO.

The edges of the side walls 9 are formed with parallel guide ribs Iextending over the rounded top 8 and slidably positioned in the channelbetween the guides is a closure l2, preferably constructed of metal andin ribbonv form and curved in conformity to the rounded'top 8, the endslof the closure extending in substantial parallelism against the sides 9as more clearly shown in Figure 4 of the drawing.

The closure 12 is provided with a slotted opendetailed explanation.

ing |3l adapted to register with the opening IO by the'sliding movementof the closure acros the rounded top of the neck. Surrounding the baseof the neck is a ring member I 4 having anv internal larcuate slot |5 atdifi r ametrically opposite sides and within each of the slots ispositioned a pin |6 projecting outwardly from the end portion of theclosure |2; The slots are of opposite inclination.

Accordingly, it will be apparent that upon the w rotation of the'ringmember 14 around the neck that the arcuate vslots 15 by reason of theirengagement with the pin |6 will cause the closure |2 to slidetransversely across the top of the neck to move the openings ID and |3into and out of 15 registering position.

It is believed the details of construction and manner of operation ofthe device will be readily understood from the foregoing without furtherHaving thus described the invention what I claim isi i 1. A paste tubeclosure comprising in combination a paste tube having a neck providedwith a rounded extremity and having a discharge opening therein, aclosure mounted for sliding movement across the rounded end of the neckand having an opening therein adapted to register with said first narnedopening, the ends of the closure extending downwardly along the side ofthe neckand a 'rotatab'le member carried by the neck and havingoperative engagement with the opposite ends of said closure to slidablyactuateV the closure.

2. A paste tube closure comprising a neck on the tube having adischarvge opening, a guide w channel on the neck extending across thetop thereof, a closure slidable in the channel for controlling theopening, a ring rotatably mounted on the neck and having oppositeinclined slots in diametrically opposite sides and pins carried by theclosure and engaged in said slots to slidably actuate the closure.

3. A paste tube closure comprising a neck on the tube having 'adischarge opening, a guide channel on the neck extending across the topthereof, a closure slidable in the channel. for
